Researchers at UT Dallas used an enzyme called TdT to create unique genetic "fingerprints" inside living cells—a breakthrough in biosecurity that could help biotech companies verify cell identity and prevent counterfeiting. The technique, published in Advanced Science, increases randomness in DNA repair to generate one-of-a-kind markers. This cropped image shows a key step—Pol X’s role in the process.

The South Island giant moa towered over New Zealand's forests for millions of years before becoming extinct within a century of Polynesian settlement around 1400 CE. Colossal Biosciences plans to resurrect the 500-pound birds using ancient DNA extracted from cave deposits and artificial egg technology. [Source image: Colossal Biosciences]
